The Moira girl, a pupil at St Patricks Academy, Lisburn, passed her foundation exam at the age of just 12.

A year or so later, a 13-year-old Summer successfully completed her intermediate exam, including a practical test in building circuits.

Of her latest achievement, her proud parents said: “She spent whole weekends and evenings revising for it and her hard work paid off.” Summer’s main radio club is Lisburn-based Lagan Valley Amateur Radio Society.

Said her parents: “She has done lighthouses on the air from Rathlin, participated in RSGB (Radio Society of Great Britain) VHF (very high frequency) field day,coming second with IVARS (Interactive Voice Alert Retrieval System) and operated a St Patrick’s Day station and worked 317 stations using (callsign) gi15yota (youngsters on the air).”
